Stability-AI/StableCascade
StableCascade
StableCascade is a generative AI system and latent diffusion framework designed for text-to-image synthesis and image-to-image transformations. It utilizes a multi-stage cascade architecture that encodes and decodes images via a latent space to produce high-fidelity visual imagery.
The system includes a cascade diffusion pipeline for controlling image structure through inpainting, outpainting, and super-resolution. It also provides a toolkit for image-to-image generation and the creation of image variations using embeddings.
The framework supports model optimization through low-rank adaptation for fine-tuning new concepts, as well as scripts for training diffusion models and autoencoders from scratch. Additional capabilities cover image latent encoding and decoding to manage high-resolution visual synthesis.
